The excellent answer here no longer works in Firefox 117.0 on MacOS. Unfortunately, that post is archived, so I cannot post an updated solution there. I would greatly appreciate if a moderator could add this post in the linked article, or at least link from there over to here.

For Firefox 117, the code needs to be modified slightly (two lines at the top need to be removed): ```

  //
  function ConfigJS() { Services.obs.addObserver(this, 'chrome-document-global-created', false); }
  ConfigJS.prototype = {
   observe: function (aSubject) { aSubject.addEventListener('DOMContentLoaded', this, {once: true}); },
   handleEvent: function (aEvent) {
     let document = aEvent.originalTarget; let window = document.defaultView; let location = window.location;
     if (/^(chrome:(?!\/\/(global\/content\/commonDialog|browser\/content\/webext-panels)\.x?html)|about:(?!blank))/i.test(location.href)) {
       if (window._gBrowser) {
         let keys = ["key_find", "key_findAgain", "key_findPrevious", "key_gotoHistory", "addBookmarkAsKb", "bookmarkAllTabsKb", "showAllHistoryKb", "manBookmarkKb", "viewBookmarksToolbarKb", "key_savePage", "key_search", "key_search2", "focusURLBar", "focusURLBar2", "key_openDownloads", "openFileKb", "key_reload_skip_cache", "key_viewSource", "key_viewInfo", "key_privatebrowsing", "key_quitApplication", "context-bookmarklink"];
         for (var i=0; i < keys.length; i++) {
            let keyCommand = window.document.getElementById(keys[i]);
            if (keyCommand != undefined) { 
               keyCommand.removeAttribute("command"); 
               keyCommand.removeAttribute("key"); 
               keyCommand.removeAttribute("modifiers"); 
               keyCommand.removeAttribute("oncommand"); 
               keyCommand.removeAttribute("data-l10n-id"); 
            }
         }
       }
     }
   }
  };
  if (!Services.appinfo.inSafeMode) { new ConfigJS(); }

```

Chosen solution

That is this question:

You need to remove/replace this line as Services.jsm is no longer supported.

const {Services} = Components.utils.import('resource://gre/modules/Services.jsm');

Use this instead:

const Services = globalThis.Services || ChromeUtils.import("resource://gre/modules/Services.jsm").Services;

Thank you! I indeed forgot to link the question, my bad. In my case I did not have to add your corrected line, removing it entirely worked out. I suspect there are other cases where it is needed.
